In the framework of the Agreement of International Committee on Weights and Measures on Mutual Recognition of national standards, calibration and measurement certificates issued by national metrology institutes (NMIs), key comparisons serve as the basis for establishing calibration and measurement capabilities of NMI with implemented quality management system. On this basis, the competence of a specific NMI to perform calibration of working standards and measuring instruments for the customer laboratories is determined. In order to attract as many NMIs as possible to participate in key comparisons of standards, Regional Metrology Organizations are widely involved in conducting such comparisons. The practical application of traditional evaluation the results of key standards comparisons and displaying them in the special database of key comparisons (KCDB) of International Bureau on Weights and Measures (BIPM) may be difficult for some NMIs and for national laboratories accredited by national accreditation bodies that wish to use NMI calibration services. This is due to the fact that the KCDB BIPM only displays the degree of equivalence of a NMI standard with corresponding expanded uncertainty without any other characteristics for evaluating calibration or measurement capabilities. The paper presents a proposed alternative evaluation of results of key comparisons of standards, which simplifies the analysis of calibration services by NMIs. It envisages the use as a criterion of consistency of the results obtained from the comparisons of the En index to analyze the degree of equivalence of the NMI standard and the corresponding extended uncertainty. The practical application of the evaluation for results of key comparisons of standards of electric power is considered. This contributes to a more streamlined calibration of work standards for specific established purposes for both NMIs and accredited laboratories.

The approach to creating standard means for reproducing units of volumetric activity of radon and thoron and flux density of radon from the soil surface is described based on the physical principles of reproducing these units of quantities and using as technical means for reproducing bubblers with a radioactive solution of radium salt, reference capacities of known volume, emanation chambers for generation of a toron, a gamma spectrometer with a semiconductor detector from highly pure germanium and radon radiometers. Reproduction consists in the physical realization of units in accordance with their definition as applied to the formation of radon and thoron in the radioactive rows of radium and thorium. The proposed approach will allow to determine the structural, structural and other technical solutions of standard measuring instruments, as well as specific techniques and methods of working with them. The creation of standard tools and technologies for reproducing units of volumetric activity of radon and thoron and the density of radon flux from the soil surface will ensure the unity and reliability of measurements in the field of ionizing radiation, traceability of units and bringing the characteristics of national standards in line with world achievements.

INTRODUCTION:The Spanish National Network (REDETS) is a group of eight agencies, units and services, depending on National and Regional Governments that coordinate their work within a common methodological framework, guided by the principles of mutual recognition and cooperation. The necessity of considering a Quality Management System has been detected and, consequently, a common tool for all the members needs to be developed. We describe in this study the process to achieve that goal.METHODS:Based on both a review of previous literature and the proposal for a self-evaluating tool, a group of experts from each agency through consensus have developed a tool for self-evaluation in Health Technology Assessment (HTA) agencies. Through the structure described in the handbook of the Andalusian Agency for Healthcare Quality (ACSA), each standard should have a statement or proposal that needs to also include evidence or good practices, and the corresponding evaluation questions. In separate workgroups, the definition of these proposals, evidence and evaluation questions were developed. One face-to-face meeting and two meetings via teleconference were necessary to achieve a final document with all the quality standards.RESULTS:From a proposed structure of sixty-six standards, the titles, definitions, statements and evidence as well as good practices and evaluation questions were established in workgroups with consensus among all of the members (1 - 3). The final version of the self-assessment tool was composed of sixty-eight standards, grouped in twelve quality criteria structured in four dimensions: I Responsibility, II Clients and Stakeholders, III Production Process, and IV Resources.CONCLUSIONS:Quality management requires an evaluation tool and this version, based on a systematic review and consensus, is a useful and practical instrument for developing a handbook by each member of REDETS. An online version of the tool is in process of development.

IntroductionThe Spanish network of health technology assessment (HTA) agencies (REDETS) is a collaboration of eight agencies, units and services, commissioned by the national and regional governments. The network coordinates work within a common methodological and work framework, guided by the principles of mutual recognition and cooperation. In 2016, a common self-assessment quality tool was developed for the implementation of an overall Quality Management System. Currently we are working on the second step that deals with actions about management, joint activities as a network, and organizational aspects of the network.MethodsA structured search strategy in the main electronic databases and a manual search in websites of networks national and international agencies were carried out in June 2017, in order to gather previous knowledge and developed standards. Through the information included in this review, and with the collaboration of all members, a group of standards for REDETS was developed. Finally, standards proposed were discussed in a face-to face meeting until an agreement was reached.ResultsA proposal of 31 standards was put forward taking all the collected information. The aim of each standard was defined, and its level of compliance was specified. Those standards were grouped under nine quality criteria structured in four dimensions: (i) Responsibility and Resources, (ii) Performance and Membership, (iii) Procedures, and (iv) Relations.ConclusionsBased on the gathered information and the agreement of the all members, we developed a toolkit embracing a group of standards for the joint activities within the Spanish Network, network administration and management. It is a complementary instrument of the previous self-evaluating tool, following the establishment of an overall quality management system and under the philosophy of continuous improvement processes.

A quality system for production software should be part of the quality management system of an organization and can be expressed as objectives in the form of processes, procedures, tools and responsibilities, designed and developed to fulfil the quality requirements. These usually are addressing the customers (external or internal), compliance with standards (effectiveness) waste reduction and better use of resources (efficiency) for continual improvement. Such systems are designed according to the requirements of the standards for quality management, software engineering and information security. Quality systems themselves could not provide all necessary means for driving the organization to the quality and excellence of a product. Still there are some gaps in the processes which are not covered by too generic standards and it is the organizational ability to cover the gaps in an appropriate way. The aim of this paper is to examine the effectiveness of our proposed conceptual QSPS model to reduce the gaps in the processes of an organization by enhancing the quality of production software. In order to achieve that goal, a mathematical representation of QSPS has been derived and an evaluation has been realized among different software quality methods. The reliability and validity of the QSPS has been examined through the practical application to the automotive industry considering the elements like: (i) Planning, time and cost evaluation (ii) Software requirements (management, risk, quality and security) (iii) Validation and verification of the implemented software before release (iv) Internal release of the software (v) Client release of the software (vi) Functional monitoring after release in the production and continuous improvement process (vii) Customer satisfaction. The results of mathematical simulation and practical application revealed that the proposed QSPS model showed superior phenomena compared with other known software quality methods and also expressed significant advantages, while using it on the production software. So, an effective application of QSPS would result in the smooth running of the production software to get a high quality product according to customer and standard requirements.

PurposeThe purpose of this paper is to report the first practical applications of FCAUP (Framework for Conformity Assessment inspired by the Uncertainty Principle) carried out using a pilot implementation in a boat trailer manufacturer company in Maryville, Tennessee, USA and a practical application in a metrology company in São José dos Campos, São Paulo, Brazil.Design/methodology/approachField studies have been conducted in two different companies: a pilot implementation during the preparation activities of the acceptance inspection of finished products and a practical application during the internal audit related to the quality management system.Findings(1) partial double inspection is advantageous in conformity assessment; (2) a structured procedure tends to reduce the risks arising from the use of partial double inspection; (3) the recommended amount of double inspections is directly proportional to the uncertainty involved in the process and it is inversely proportional to the degree of trust in a presumed conformity status.Research limitations/implicationsThis novel framework is for practitioners in manufacturing industries and test laboratories.Practical implicationsThe results of these practical applications suggest that FCAUP is a consistent approach to be used in several categories of conformity assessment in manufacturing industries and test laboratories due to the balance between result and time (cost).Originality/valueThis new framework, named FCAUP, for planning and executing conformity assessment activities has been introduced in a theoretical study published by Moraes and Silva (2018) and it is based on an analogy with the Uncertainty Principle of Quantum Mechanics.

Abstract In the work, there was a method of problems examination presented in the certified quality management system according to the ISO 9001 standard. The own method of problems examination was suggested on the basis of reports from audits of the third party. There are method assumptions as well as practical application presented for the examination of nonconformities and weaknesses on a sample of 892 organizations certified by a chosen certifying body. Different types of compilations of obtained results are showed. Different possibilities of their application for the examination of relations of identified problems were indicated, depending on the size and profile of examined organizations. Different types of statistical tests were used in the method together with their possibilities. Concrete examples of uses of the method and statistical tests were provided for examining the relations between the size as well as profile of the organization and the number as well as type of nonconformities and weaknesses. It was attempted to determine what possibilities the method provides and to give the examples of its practical use. Additionally, an attention was paid to potential difficulties when applying the method.

Rapid advances in technology-communications, the internet, tele-marketing, travel, etc. are accelerating the globalization of the world’s market places. To facilitate this globalization by eliminating measurement-based barriers to trade, the International Committee on Weights and Measures (CIPM) has, in accord with the authority granted it by the International Treaty of the Meter, produced a Mutual Recognition Arrangement (MRA). This MRA, signed into existence in Oct 1999, has the objectives: 1. to establish the degree of equivalence of national measurement standards maintained by the National Metrology Institutes (NMIs) that have signed the MRA, 2. to provide for the mutual recognition of calibration and measurement certificates issued by the NMIs, and thereby 3. to provide governments and other parties with a secure technical foundation for wider agreements regarding measurements that relate to international trade, commerce, and regulatory affairs. Information on the CIPM, and the MRA can be found on the website: http://www.bipm.org/. Degrees of equivalence between and among national measurement standards are based on the results of Key Comparisons (KCs) conducted within the Consultative Committees of the CIPM. Flow measurement efforts are being addressed by the newly formed Working Group for Fluid Flow (WGFF) of the CIPM Consultative Committee on Mass and Related Quantities (CCM). The WGFF efforts are organized into six, specific measurement areas: water, hydrocarbon liquid, air speed, liquid volume, high pressure gas, and low pressure gas flow. In each of these areas, and according to MRA rules, the efforts are to design and conduct KCs that quantify the equivalence of the flow standards maintained in the participating NMIs. To determine appropriate operating ranges for KC’s, the WGFF is reviewing the Calibration and Measurement Capabilities (CMCs) of the participating NMIs. This presentation will briefly describe the MRA and the current WGFF plans and programs to conduct the KC tests. Specific techniques planned for the KCs will be to design flow meter transfer standards comprised of tandem arrangements of flow meters that are tested in the selected fluid and flow conditions to quantify the performance of NMI flow standards under actual conditions of use. Statistically sufficient and metrologically sound test protocols are being devised to efficiently and effectively produce the required data bases. Youden graphical analysis of variance and other statistical techniques are planned to analyze the resulting data. The results of these WGFF efforts are expected to make it feasible for flow measurements made anywhere in the world to be understood and acceptable anywhere else.

The results of additional bilateral comparison of initial standards of the impulse electrical voltage unit were considered. As a result of comparison there were confirmed announced uncertainties and calibration and measurement capabilities of the participants of comparison. The comparison was carried out under guidance of COOMET (project 710/RU-a/16) оn the initiative of national metrology institutes (NMI): VNIIFTRI (Russia) and BelGIM (Republic of Belarus). The comparison involved national standards: the State primary standard unit of the impulse electrical voltage unit (GET 182-2010, VNIIFTRI) and the original standard of the impulse electrical voltage unit BelGIM. Step pulse generator TMG030010SN11-M1 was used as a traveling standard. The values of the impulse electrical voltage, reproduced by means of traveling standard, were measured by national standards.The purpose of comparison was to confirm confidence in the measurement results and calibration certificates, issued by the NMI in the field of impulse electrical voltage measurements. In the comparison VNIIFTRI acted as a pilot laboratory. Measurements of impulse electrical voltage by means of traveling standard were carried out in the following order: first – measurements of impulse electrical voltage on GET 182-2010, then – on the original standard of BelGIM and finally – again on GET 182-2010. Processing of the results of comparison according to χ2(i) criterion showed that χ2(i) criterion values (calculated on the basis of the measurement results) doesn’t exceed a critical value χ2, that is the objective confirmation of announced uncertainties, declared by the participants of comparison.
